Everything you ever wanted to know about moles (but were too busy on the sunbed to ask)

They can be perfect beauty spots or unsightly but benign blemishes, yet moles can also become cancerous. So what signs should you look out for?

The average adult has between 10 and 40 moles, whether they are perfectly placed beauty spots, or unloved hairy blemishes. Because of their association with skin cancer, moles are often seen as a direct result of sun exposure but, while it is thought that UV light can contribute to moles forming, it isn’t unusual to be born with them.
